I5-2500k @ Stock Speeds Idling High with Aftermarket Cooler

Hi there,

I'm running an i5-2500k on my aftermarket cooler, this one (http://www.newegg.com/Product/Product.aspx?Item=N82E16835185142) and I'm using this fan on it (http://www.newegg.com/Product/Product.aspx?Item=N82E16835608004) instead of the stock one that it came with. Now, I'm just wondering why is it idling at 37c-41c at room temperature inside my HAF 922 with the case side closed? I'm really confused because when it starts up, it's idling at ~32c, but then overtime, it just gradually gets up to the point of where it stays at that temperature. Oh, and if this is anything, it's only at about ~46c-54c while I'm running Battlefield 3.

Checking Task Manager, my CPU usage is really around 10-12% while I'm writing this.

  1. its because automatic fan speeds keep the fans low to lower noise and power use unless you need it. Why does idle temperature matter that much?
  2. ~5-10C above roomtemp at idle is normal. Your gaming temps are fine so I'm going to assume load temps are good and that is really all that matters.
